Water-Quality Data Exchange
Data format based on USEPA Water Quality Exchange (WQX) (NWQMC WQ Data Elements)
Common definitions and semantics EPA’s Substance Registry System for chemicals Chemical groups Site types Sampling media Taxonomy
Common web services for serving Monitoring Locations and Water-Quality Results
Project Objectives
1) Common format and nomenclature
2) Web services to serve monitoring data
3) Services for users to find sites and data
4) Portal to merge disparate web service feeds

Hydrology Domain Working GroupHydrology Domain Working Group
• A joint working group of the OGC and WMO constituted as an OGC Domain Working Group.
• Brings together interested parties to develop and promote the technology for greatly improving the way in which water information is described and shared.
• Co-chaired by representatives nominated by the OGC TC and the World Meteorological Organisation’s (WMO) Commission for Hydrology (CHy).
• Current Co-Chairs: Ilya Zaslavsky (SDSC), Ulrich Looser (GRDC) and David Lemon (CSIRO)
• > 50 Participants, > 30 Organisations

Expected OutcomesExpected Outcomes• An agreed feature model (ie. what are the features of the
hydrosphere (from an information perspective) and how are they related.)
• An agreed observation model. • Agreed vocabularies, endorsed by the community, and by
WMO in particular. Agreeing on semantics is a long process, but we should be able to recommend some vocabularies
• Also: services carrying the above
Groundwater Data Exchange – OGC/WMO HydroWG Interoperability Experiment
Test and enhance OGC standards for water observations
Exchange groundwater well characteristics and water levels with Canada
Next steps: streamflow, water-quality
